Electronic signature software, open source and built into your ERP
Sign documents online, reuse templates, and automate approval workflows with a full audit trail and legal validity. This is electronic signature software that starts from your sales quotations, HR records and contracts, not another standalone signing app with per-envelope fees.
Sign from your ERP · Legally valid (eIDAS / ESIGN) · Free plan to start
Send, sign and track documents from one workspace
Designed for companies that need document signing connected to their business workflows, not just a standalone PDF tool.
Reusable document templates
Create templates once, use them every time.
Upload PDF files, configure signature fields, and save templates for future use. They link automatically to the corresponding ERP records streamlining the signing process without manual work.
Role-based signer assignment
Define signing roles for each template and ensure the right people are assigned automatically based on predefined criteria. Configure custom roles for employees, vendors, or customers with full flexibility.
From request to signed, without the chase
Sign one document or hundreds, keep a defensible record of every action, and let the finished file file itself.
Individual or bulk signing
Sign from templates with predefined roles, or select many records and send mass signing requests in one click.
Full audit trail
Every action is logged with date, time and signer identity, with tamper-evident proof of who signed, when and from where.
Auto-completion & archiving
Once all signatures are in, a finalized PDF is generated automatically — ready to use or store in Documents.
Where teams use electronic signatures
Because Sign lives in the ERP, the document starts where the work happens and comes back signed, attached to the right record.

Send sales quotations and contracts for signature and close deals faster from your CRM.
HR onboarding
Get employee contracts, policies and onboarding documents signed no paper, no trips.

Is an electronic signature legally binding?
Sign generates simple electronic signatures (SES), which produce legal effects and are admissible as evidence in court:
eIDAS (EU): valid across all 27 member states; a signature can't be denied legal effect just for being electronic.
ESIGN Act + UETA (US): the federal and state framework that gives electronic signatures legal standing.
Tamper-evident audit trail: timestamped access logs with IP and signer identity, plus cryptographic proof that detects any alteration.
This is general information, not legal advice; specific validity depends on your country's law and use case.
Binhex Sign vs DocuSign and standalone tools
Standalone signing tools do one thing well. The difference is where the document lives before and after it's signed.
